SPECIFICATION forming part of Letters Patent No. 254,598, dated March 7, 1882.

Application filed December 16, 1881. (No model.)

To alt whom it may concern Beit known that I, HENRY RAMMEL ALvEs BOYS, of Barrie, in the Province of Ontario and Dominion of Canada, have invented a new and useful Improvement in Lubricators, of which the following is a full, clear, and exact description.

My improvements relate generally to that class of lubricators for engine-cylinders oper-- ated by condensing steam.

The invention consists in a novel construction and arrangement of the parts, as hereinafter described, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a front elevation of my improved lubricator. Fig. 2 is a longitudinal section, showing the condensing-cylinder, regulatingplug, exit-passage for air and gas, andthe supplementary condenser. Fig. 3 is a sectional view of the lubricator as arranged with a horizontal condenser.

Referring to Figs. 1 and 2, B is the condensing-chamber, provided with cap a.

V is the oil-flask on which the cylinder is connected.

T is the valve for shutting oft' the pressure when the ask has to be filled.

A is the passage in the connection H of the chamber B between the lubricator and steampipe D.

C is the regulating-plug, formed with an eX- terior screw-thread, taking a similar thread on the sides of chamber B, so that the plug may be adjusted to increase the space between the upper end and cap a to the largest extent, as shown in full lines, or diminished to the smallest extent, as shown in dotted lines.

E is a passage through plug C, to allow passage of water to the flask, the passage being enlarged in square form,'as shown at F, to receive a wrench for turning the plug.

G is a slot through the wall of the condensing-chamber into the passage A.

J is a passage from the upper end of slot G, where the air and gas accumulate, to the steampipe D, for exit of the gas and air.

L is a projection on the lower part of the passage A, connecting the condensing-chamber and steam-pipe, extending into the steampipe, so as to deiiect the steam into the passages faster than required by condensation, and thereby cause the ejecting of the air and gas through the passage J to the steam-pipe.

M is a passage from cylinder B to the bottom of drop-tube 0, and N is a cock tted in the passage for closing it when required.

P is a centrally-apertured' disk at the bottom of tube o, for causing the oil to rise at the center.

Q is a connection between tube o and passage A.

R R are the packing-glands of the tube.

S is a bridge on the wall of cylinder B, left in forming slot G, to prevent any water of condensation passing from the passages to the condensingchamber.

X is the supplementary condenser, attached to an apertured nipple on the side of cylinder Bby a packed joint, which permits the chamber X to be turned to a horizontal position for discharge of its contents to the main chamber. This insures an increased iiow of oil, and the chamber will, on being returned to a perpendicular position, gradually fill again; or it may be left in a horizontal position to serve as an enlargement of the main supplemental condensing-chamber; or it may be made to bold a large quantityV of oil or water, and be lled through an opening, ready for use at any time a larger supply than usual is required.

In Fig. 3 the condensing-chamber is shown horizontal. B is the condensing-chamber; G, the plug, movable to and from cap a, to vary the condensing-space and regulate the amount of water required to Work the lubricator, that condensed between the plug and steam-pipe iiowing back to the pipe.

The operation is as follows: On valve T being opened steam will iiow through the passage A to the space between plug C and cap a, and the water of condensation will pass through the plug on to the iiask, thereby causing the oil to rise and flow through passage M, drop-tube o, and passage A to the steam` pipe. The pressure or current of steam caused by its striking the projectionv L will keep the lubricator free from air and gas. In case the drop-feed fails to wolk, cock N may be closed, and in a short time the oil will rise through of the condensing-chamber to the steam-pipe above the steam-passage, and communicating with the said steam-passage at its inner end, substantially as herein shown and described, whereby the air and gas are ejected from the condenser into the steam-pipe, as set forth.

2. In a lubricator, the combina-tion, with the A condensing-chamber B, provided with the slot G and the steam-pipe D, of the connection H,

.provided with the steam-passage A, having the projection L on its lower part extending into the steam-pipe, and the air and gas passage J above said steam-passage and communicating therewith at its inner end, substantially as herein shown and described, whereby steam will be admitted faster than required and the air and gas thereby ejected, as set forth.

3. In a lubricator, the combination, with the condensing-chamber B, internally screwthreaded and provided with the slot Gr, of the apertured and externally screw-threaded plug 0, substantially as and for the purpose set forth.

4. In a lubricator, the combination,with the condensing-chamber B, of the supplementary condensing-chamber X, pivoted to the side of the main chamber B, to adapt it to be swung in a horizontal position to empty its contents into the said main chamber, substantially as herein shown and described.
